area = π x radius2
→ radius =√(area/π)
circumference = 2 x π x radius
= 2 x π x √(area/π)
= 2 x √(area x π)
= 2 x √(121 cm2 x π)
= 22 √π cm
The circumference of a circle with an area of 121 pie yards squared (380.13 yards2) is: 69.1 yards
radius = 121/(2Ï€)
The area of a circle is given by the formula A =π r² Therefore 121π = π r² : 121 = r² : r = √121 = 11 The circumference of a circle is given by the formula C = 2πr C = 2 x 11π = 22π or 69.115 (to 3 decimal places)
Using 3.14 as Pi the area of circle is: 0
Take pi as 355/113, then area = 355 x 121/113 = 380.13 sq in. and circumference = 22 x 355/113 = 69.12 in.
The circumference of a circle with an area of 121 pie yards squared (380.13 yards2) is: 69.1 yards
The radius a circle with area of π*121 yd2 is 11 yds [= sqrt(121)] The circumference, therefore, is 2*11*π = 22*π yards.
radius = 121/(2Ï€)

Using 3.14 as Pi the area of circle is: 0
Take pi as 355/113, then area = 355 x 121/113 = 380.13 sq in. and circumference = 22 x 355/113 = 69.12 in.
the area can not be cubed. the area is always squared. volume is cubed. the formula for area is pie multiplied by radius squared. your formula for your circle is... A = 121pi in2 the radius in your circle is 11 inches the formula for circumference is two times pi times the radius C = 2 * (3.14159) * 11 your answer is 69.11498in
A circle with a diameter of 38.5 inches has a perimeter of 121 inches (approx).
6.21
Circumference not required, and in any case doesn't make sense for a radius of 11; it should be 69. A = pi x r x r = 121 pi = 380.12
Radius = 6.21
